WILLIAM B. SHORLAND, OF MANCHESTER, ENGLAND.

KNOB ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 250,588, dated December6, 1881.

Application filed May 7, 1881. (Model.) Patented in England J nne 24,1880, in Belgium December 22, 1880, in France December 22, 1880, and inGermany December 29,3880.

To all whom it may concern:

Be it known that I, WILLIAM B. SHORLAND, a citizen of Great Britain,residing at Manchester, in the Kingdom of Great Britain, have inventedcertain new and useful Improvements in Knob Attachments; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 is a longitudinal central section,

showing door-knobs and spindle having present invention. Fig. 2 is aplan view of one part or half of the spindle; Fig. 3, detail incross-section, line a; m, Fig. 2 5 Fig. 4, plan view of the boss; Fig.5, plan view of the rose; Fig. 6. central cross-section of Fig. 5 online y 3 Fig. 7 shows the binder-wire; Fig. 8, perspective view of thetwo parts of the spindle ad justed ready to be matched together for use,knobs shown in dotted lines.

' This invention relates to improvements in that class of; knobattachments designed more especially to enable the knobs to be fittedupon doors, drawers, or other devices of any usual or ordinarythickness; and the novelty in the present instance consists in thedetail of the construction and adjustment of the several parts, whereby,in an easy, neat, simple, and most efficient way, all the desiredresults are accomplished, as will now be more fully and in detail setout and explained.

In the accompanying drawings, A denotes any usual door or similar knob,made of metal, porcelain, or other material or substance, and B thespindle. This spindle, when used for doors, is made in two pieces, I)I), each generally like the other and having a rib, b, at the inner end,where it fits into the shank of the knob and a forked opening, 11 Thefaces at each part of the spindle may be roughened, grooved, or fluted,as shown at b, and one may have a groove, b, at the edge. When, now, thesaid two parts of the spindle are placed the one on the other to be usedin a door or like device the rib b on the end of the one fits into theopening I) in the other, and the two parts can have space vforconsiderable longitudinal movement back or forth on each other, while bythis said detail of construction and matching together the parts, whenmade of the right length and fixed together-as when in place in theknobs A and secured by screws 0, passing through the shank of the bossand the spindlewill be as firm, rigid, and strong as if they constituteda single piece. This screw cit will usually be found best to passentirely through the spindle and into the opposite side of the knob. Itmay be found best to have the head of this screw 0 press upon the forkpart of the spindle. While the abutting faces of the two parts of thespindle may be smooth if desired, it is preferred to have themroughened, as above described, to prevent their easily moving on eachother, and also to permit the use of a binder in shape of the bent wire76, one portion of which is thrust between the two parts of the spindlein any of the grooves, where they match, and the other rests in thelongitudinal groove b. In placing the knobs in position the boss Z, ofmetal preferably, having the spindle through its central opening, I, isscrewed or otherwise fixed to the face of the door or other article, andholes I are provided for this purpose. The projections m of the rose mare adapted to match with and pass through the openings l in the boss I,and thus the rose will be held firm when the parts are fixed in place asin use. One side of the boss projects into the shank of the knob, whichis recessed, as shown in Fig. 1, and keeps the spindle from wearing thedoor or drawing the works of the lock, and also prevents the knob fromshaking.

The method of applying this device to doors and for like uses will bereadily understood. They are taken, as shown in Fig. 8, and passedthrough the door and lock, one from either side, and when pressed upclose the screws 0 in the knobs are tightly screwed up, except when thewire 70 is used. Then one screw is fastened and one knob is taken off todraw the spindle out to put the wire in and then put back again.

To adapt this invention to cupboards, drawers, &c., where only one knobis used, a single spindle is fixed in the shank of the knob and fastenedby the screw 0, while in the slot in the other end of the spindle willbe fixed the turnbutton or finger O. In use this button comes on theinside of the cupboard door or drawer.

Having thus described my invention, What I consider new, and desire tosecure by Letters Patent, is-

1. In a door-knob attachment, a spindle, B, made of two parts, b b, eachhaving a boss, I), at one end, and a slot, 1), at the other,substantially as and for the purposes described.

2. In adoor-kuob attachment, the boss l, havin g screw-holes at theends, a central spindleopening, and others at the sides, combined withrose m, having projection m, substantially as described.

3. In a door-knob attachment, the binder K, in combination with theparts I) b of the spindie B, transversely grooved in their abuttingfaces at b and longitudinally grooved at b, the whole adapted togetherand operating substantially in the manner set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM BURROW SHORLAND.
